In this physical activity, two lines of learners link hands and arms to model a beam subject to various loading schemes.

In this activity learners explore surface tension. Why are certain objects able to float on the surface of water and how do detergents break the surface tension of water?

In this activity, learners experiment with surface tension using everyday household items such as strawberry baskets, paperclips, liquid dish soap, and pepper.

Learners explore how the attractive forces between water molecules create surface tension and allow certain objects to float on the surface of water.

Over the course of several days, learners explore the property of water that helps plants move water from roots to leaves or gives paper towels the capacity to soak up water.
